Ecosysème entrepreneurial local et finance participative : enjeux d’une coopération

Many academic works recount the relationship between entrepreneurship, territory and collective dynamics. Similarly, different conceptual territorial innovation models are attached to represent the link between geographic proximity, innovation and competitiveness. In France, many crowdfunding platforms have seen since 2010 to meet the difficulties of financing of innovative projects. These new players challenge existing devices to aid in the creation, development and support of innovative companies in the territories. This work seeks to understand the issues of cooperation brought about by this participatory finance in the constitution of’communities’ digital. How do the territories seek to capitalize these dynamics in a process for capturing these communities around a will of territorialized economic development ? Through an approach focused on the actors in the social economy and solidarity who, historically, organized locally to meet the diversity of the issues of territories, this research aims to answer the following question : how to organize the cooperation by stakeholders in the SSE, via participatory finance, in an entrepreneurial ecosystem ? On the one hand it’s question on how to consider cooperation in funding decisions between different actors of the entrepreneurial ecosystem in a territory, and, on the other hand, imagine how to switch from a virtual community to a community approach by the digital revolution in geographically delimited areas

Pulmonary sequestration: a review of 26 cases

OBJECTIVES: Pulmonary sequestration is a continuum of lung anomalies for which no single embryonic hypothesis is yet available. The aim of this study was to assess the diagnostic tools and treatment for the rare condition, pulmonary sequestration, in an unspecialised centre. METHODS: We performed an analysis of 26 cases of pulmonary sequestration (paediatric and adult) operated at the Centre Hospitalier Universitaire Vaudois between May 1959 and May 1997. A review of the extralobar and intralobar types of sequestrations is discussed. Angiography is compared to other diagnostic tools in this condition, and treatment is discussed. RESULTS: Twenty-six cases of pulmonary sequestrations, a rare congenital pulmonary malformation, were operated on in the defined time period. Seventy-three percent (19) of the cases were intralobar and 27% (seven) extralobar. Extralobar localisation was basal in 71% and situated between the upper and the lower lobe in 29%. In six cases, the diagnosis was made by exploratory thoracotomy. In the other 20 cases, diagnosis was evoked on chest X-ray and confirmed by angiography. Lobectomy (46%) was the most common treatment procedure. Segmental resection was performed in 30% of the cases and bilobectomy in 4%. Post-operative morbidity was low. The most significant complications were pleural empyema, haemothorax and haemopneumoperitoneum in case of extralobar sequestration. There was no evidence of metaplasia or pre-neoplastic changes. CONCLUSIONS: Despite its rarity, some radiological features are sufficiently suggestive of diagnosis of pulmonary sequestration. Investigations are necessary in order to avoid unexpected pathology at the time of operation. Resection of the involved lung leads to excellent results and the long-term outcome is highly favourabl

Arthropod distribution in a tropical rainforest: tackling a four dimensional puzzle

Quantifying the spatio-temporal distribution of arthropods in tropical rainforests represents a first step towards scrutinizing the global distribution of biodiversity on Earth. To date most studies have focused on narrow taxonomic groups or lack a design that allows partitioning of the components of diversity. Here, we consider an exceptionally large dataset (113,952 individuals representing 5,858 species), obtained from the San Lorenzo forest in Panama, where the phylogenetic breadth of arthropod taxa was surveyed using 14 protocols targeting the soil, litter, understory, lower and upper canopy habitats, replicated across seasons in 2003 and 2004. This dataset is used to explore the relative influence of horizontal, vertical and seasonal drivers of arthropod distribution in this forest. We considered arthropod abundance, observed and estimated species richness, additive decomposition of species richness, multiplicative partitioning of species diversity, variation in species composition, species turnover and guild structure as components of diversity. At the scale of our study (2km of distance, 40m in height and 400 days), the effects related to the vertical and seasonal dimensions were most important. Most adult arthropods were collected from the soil/litter or the upper canopy and species richness was highest in the canopy. We compared the distribution of arthropods and trees within our study system. Effects related to the seasonal dimension were stronger for arthropods than for trees. We conclude that: (1) models of beta diversity developed for tropical trees are unlikely to be applicable to tropical arthropods; (2) it is imperative that estimates of global biodiversity derived from mass collecting of arthropods in tropical rainforests embrace the strong vertical and seasonal partitioning observed here; and (3) given the high species turnover observed between seasons, global climate change may have severe consequences for rainforest arthropods1012CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQSolVin-Solvay SA; Smithsonian Institution; Smithsonian Tropical Research Institute; United Nations Environment Programme; Smithsonian Institution; Smithsonian National Museum of Natural History; European Science Foundation (ESF); Global Canopy Programme; Czech Science foundation GACR grant; European Social Fund (ESF); Ministry of Education, Youth & Sports - Czech Republic; French National Research Agency (ANR); Research Council of Norway; Grant Agency of the Czech Republi

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

Choosing and Using a Plant DNA Barcode

The main aim of DNA barcoding is to establish a shared community resource of DNA sequences that can be used for organismal identification and taxonomic clarification. This approach was successfully pioneered in animals using a portion of the cytochrome oxidase 1 (CO1) mitochondrial gene. In plants, establishing a standardized DNA barcoding system has been more challenging. In this paper, we review the process of selecting and refining a plant barcode; evaluate the factors which influence the discriminatory power of the approach; describe some early applications of plant barcoding and summarise major emerging projects; and outline tool development that will be necessary for plant DNA barcoding to advance

Second asymptomatic carotid surgery trial (ACST-2): a randomised comparison of carotid artery stenting versus carotid endarterectomy

Background: Among asymptomatic patients with severe carotid artery stenosis but no recent stroke or transient cerebral ischaemia, either carotid artery stenting (CAS) or carotid endarterectomy (CEA) can restore patency and reduce long-term stroke risks. However, from recent national registry data, each option causes about 1% procedural risk of disabling stroke or death. Comparison of their long-term protective effects requires large-scale randomised evidence. Methods: ACST-2 is an international multicentre randomised trial of CAS versus CEA among asymptomatic patients with severe stenosis thought to require intervention, interpreted with all other relevant trials. Patients were eligible if they had severe unilateral or bilateral carotid artery stenosis and both doctor and patient agreed that a carotid procedure should be undertaken, but they were substantially uncertain which one to choose. Patients were randomly allocated to CAS or CEA and followed up at 1 month and then annually, for a mean 5 years. Procedural events were those within 30 days of the intervention. Intention-to-treat analyses are provided. Analyses including procedural hazards use tabular methods. Analyses and meta-analyses of non-procedural strokes use Kaplan-Meier and log-rank methods. The trial is registered with the ISRCTN registry, ISRCTN21144362. Findings: Between Jan 15, 2008, and Dec 31, 2020, 3625 patients in 130 centres were randomly allocated, 1811 to CAS and 1814 to CEA, with good compliance, good medical therapy and a mean 5 years of follow-up. Overall, 1% had disabling stroke or death procedurally (15 allocated to CAS and 18 to CEA) and 2% had non-disabling procedural stroke (48 allocated to CAS and 29 to CEA). Kaplan-Meier estimates of 5-year non-procedural stroke were 2·5% in each group for fatal or disabling stroke, and 5·3% with CAS versus 4·5% with CEA for any stroke (rate ratio [RR] 1·16, 95% CI 0·86–1·57; p=0·33). Combining RRs for any non-procedural stroke in all CAS versus CEA trials, the RR was similar in symptomatic and asymptomatic patients (overall RR 1·11, 95% CI 0·91–1·32; p=0·21). Interpretation: Serious complications are similarly uncommon after competent CAS and CEA, and the long-term effects of these two carotid artery procedures on fatal or disabling stroke are comparable.
